<p>Pressure sensitive adhesives, and tackified pressure sensitive adhesives, and viscoelastic materials that are the polymerization product of an acrylic acid ester of a monohydric alcohol whose homopolymer has a Tg less than 0 °C; a non-polar ethylenically unsaturated monomer whose homopolymer has a solubility parameter of no greater than 10.50 and a Tg greater than 15 °C; and 0 - 5 parts by weight of a polar ethylenically unsaturated monomer whose homopolymer has a solubility parameter of greater than 10.50 and a Tg greater than 15 °C.</p> |
